Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed September 22,1905. Serial No. 279.632.

To all whom it may concern;

Be it known that I, HENRY A. SWANTON, a citizen of the United States, residing at Roxbury, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Engines, of which the following is a specification.

This invention relates to improvements in engines, particularly to the casings of engines, whereby the oil which is detached from moving parts is confined within the casing and said moving parts are inclosed thereby in such a manner that the exterior of the engine is kept free from oil and dirt, and thus presents at all times a neat and clean appearance.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings, Figure 1 is a side elevation, partly broken away and shown in section, of a steam-engine with my improved casing attached thereto. Fig. 2 isan end elevation of the same, partly broken away and shown in section. Fig. 3 is a detail section taken on line 3 3 of Fig. 1, illustrating the casing and manner of attaching the same to the rectangular frame-rods. Fig. 4 is a detail section, partly in elevation, taken on line 4 4 of Fig. 1, illustrating one of the catches by means of which the two side sections of the casing are attached to the frame of the engine. Fig. 5 is a detail section taken on line 5 5 of Fig. 1, illustrating the manner in which the innerand outer sheets of metal of which the casing is formed are joined together. Fig. 6 is a detail section similar to Fig. 3, illustrating a modified form of easing frame-rod. Fig. 7 is a section similar to Fig. 3, illustrating an additional oilguard attached to the casing.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 8 is the cylinder, 9 the piston, and 10 the piston-rod, of a steam-en gine. 11 is the cross-head, 1.2 the connectingrod, 13 the crank, and 14 the crank-shaft, of said engine. The crank-shaft 14 is journaled in bearings provided in the bed 15 and has fast thereto a fly-wheel 16. A valve 17 is connected by a valve-rod 18 to a slide 19, operated by an eccentric-rod 20 and eccentric 21, said eccentric 21 being fast to the main shaft 14. The cylinder 8 and bed 15 are fastened together by a frame 22, formed of rods which are rectangular in cross-section and which are fastened to said bed and cylinderhead by nuts.

The space between the cylinder 8 and the bed 15, in which the different moving parts hereinbefore enumerated are located, is surrounded, andsaid parts are inclosed within a casing 23. Said casing consists oftwo end sections 24 25 and two side sections 26 27. Each of the casing-sections hereinbefore referred to is formed of two sheets of metal which are fastened together by rivets 28 28, the rivets 28 each being surrounded by a sleeve 29 in order to hold the two sheets of metal apart and provide therebetween an air-space. The outer sheet metal of the end sections 24 and 25 extends outside the four rectangular upright rods 22 22, about halfway thereacross, and is screwed to said rods, as illustrated in Fig. 3.

The side sections 26 and 27 are each provided with catches 30, said catches comprising a spindle 31, journaled to rotate in said. side section and having a handle 32 formed upon the outer end, while the inner end has fastened thereto a sleeve 33, provided with a lateral projection 34, so that when the handle 32 is rotated the projection 34 will engage the inner face of the rod 22 to disengage said projection from said rod. The handle 32 is rotated in the proper direction until said projection passes out of engagement with said rod, and by rotating the different catch-handles in the proper direction the sides become disconnected from the rods and may be readily removedv from the machine.

The end and side sections are each provided along their upper edges with metal bands 38, which are screwed to the cylinder, and the side sections 26 and 27 are also provided with vertical metal bands or strips 39 upon their opposite edges, which project across and cover the spaces between the adjacent edges of the side and. end sections.

The cylinder-casting 8 is provided with grooves or recesses 35, extending around the base of said cylinder, into which the upper edges of the end. and side sections project, and the bed 15 is provided with a recess 36 in. its upper edge, into which the outer sheet of the side and end sections projects, while the inner sheet of said end and. side sections projects downwardly along its lower edge against the inner face of a rib 37, which extends inwardly from the upper edge of said base adj acent to said. recess 36.

ICO

In the operation of the engine any oil which is thrown outwardly from the moving parts, such as the connecting-rod 12 and crank 13, will strike against the inner face of the inner sheet of the side or end sections, and the larger amount of oil thus thrown out by the moving parts of the engine will be prevented by said inner sheet of said sections from passing outwardly to the exterior of the machine, the same passing downwardly along the inner face of said sheet and dropping off into the bed of the machine inside the inner face of the rib 37. If, however, any of the oil should pass through between the upper or lower edges of said inner sheet and the cylinder or bed, respectively, it will remain inside the airspace located between the inner and outer sheets of said sections. This amount would necessarily be very slight, and thus the outer sheet would still afford a complete means for preventing said oil and any dirt which may adhere thereto from appearing upon the outside of the casing, bed-plate, and cylinder.

- Thus it will be seen that said casing is so con structed as to prevent any oil or dirt passing from the interior of the casing and collecting upon the outside of said casing or of the bed plate and cylinder, so that an engine fitted with my improved double casing will always present a clean and sightly exterior.

In Fig. 6 I have illustrated my improved casingattached to frame-rods 22, provided upon opposite sides thereof with recesses 40 41, into which the inner sheet of the side and end sections respectively projects, the object of this construction being to still further guard against the oil passing from the interior of the casing to the exterior thereof, the construotion illustrated in Fig. 6 being especially adapted for use in engines using forced lubrication, the shoulders 42 and 43 acting as a guard to prevent said oil from passing through the joint between the edges of the inner sheet and the casing-rods 22. i

In Fig. 7 another means for guarding against the oil passing from the engine and between the inner sheet of the casing-sections and frame-rods 22 is illustrated, the same consisting of angle-irons 44 fast to said framerods and forming guards to prevent the oil from passing between the inner sheet of the casing-sections and the frame-rods.

Having thus described my invention, what I claim, and desire by Letters Patent to secure, is
